Abstract: The present invention relates to novel esterase, more particularly to esterase variants having improved thermostability compared to the esterase of SEQ ID No 1 and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate.

Abstract: The present invention relates to a process for degrading plastic, wherein said plastic products are selected from plastic and/or textiles comprising polyester comprising at least a terephthalic acid monomer. The process of the invention particularly comprises a step of enzymatic depolymerization implemented in acidic conditions at a pH between 3 and 6.

Abstract: The present invention relates to the use of specific enzymes, more particularly of specific esterases having a polyester degrading activity, for the degradation of polyester or polyester containing material in acidic conditions at a pH between 3 and 6. The present invention also relates to a process for degrading polyester or polyester containing material, such as plastic products, comprises a step of enzymatic depolymerization implemented in acidic conditions at a pH between 3 and 6. The process of the invention is particularly suited to degrade polyethylene terephthalate, and polyethylene terephthalate containing material.
